gensprep(8) ICU 72.1 Manual gensprep(8)

NAME

gensprep - compile StringPrep data from files filtered by
filterRFC3454.pl

SYNOPSIS

gensprep [ -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright ] [
-s, --sourcedir source ] [ -d, --destdir destination ]

DESCRIPTION

gensprep reads filtered RFC 3454 files and compiles their information
into a binary form. The resulting file, <name>.icu, can then be read
directly by ICU, or used by pkgdata(8) for incorporation into a
larger archive or library.

The files read by gensprep are described in the FILES section.

OPTIONS

-h, -?, --help
Print help about usage and exit.

-v, --verbose
Display extra informative messages during execution.

-c, --copyright
Include a copyright notice into the binary data.

-s, --sourcedir source
Set the source directory to source. The default source
directory is specified by the environment variable ICU_DATA.

-d, --destdir destination
Set the destination directory to destination. The default
destination directory is specified by the environment variable
ICU_DATA.

ENVIRONMENT

ICU_DATA Specifies the directory containing ICU data. Defaults to
${prefix}/share/icu/72.1/. Some tools in ICU depend on the
presence of the trailing slash. It is thus important to
make sure that it is present if ICU_DATA is set.

FILES

The following files are read by gensprep and are looked for in the
source /misc for rfc3454_*.txt files and in source /unidata for
